What are the commonly used shutdown commands in Linux
This article is about what the shutdown commands are commonly used in Linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
In the Linux system, if you want to shut down, you can use: shutdown, halt, poweroff, reboot command.
Shutdown command
Shutdown will schedule a shutdown time for the system. It can be used to stop, shut down, and restart the machine.
You can specify a time string (usually now or hours / minutes with hh:mm) as the first parameter. You can also set up a broadcast message to be sent to all logged-in users before the system shuts down.
Important: if the time parameter is used, the / run/nologin file will be created 5 minutes before the system shuts down. To make sure no one can log in again.
Example of the shutdown command:
# shutdown# shutdown now# shutdown 13:20 # shutdown-p now# shut down the machine # shutdown-H now# stop the machine # shutdown-r09now# 35 # restart the machine in 09:35am
To cancel the impending shutdown, simply enter the following command:
# shutdown-chalt command
Halt notifies the hardware to stop all CPU functions, but still keeps the power on. You can use it to keep the system in a low-level maintenance state.
Note that in some cases it will shut down the system completely. The following is an example of the halt command:
# halt # stop the machine # halt-p # shut down the machine # halt-- reboot # restart the machine poweroff command
Poweroff sends an ACPI signal to notify the system to shut down.
The following is an example of the poweroff command:
# poweroff # shut down the machine # poweroff-halt # stop the machine # poweroff-reboot # restart the machine reboot command
Reboot notifies the system to restart.
# reboot # restart the machine # reboot-halt # stop the machine # reboot-p # shut down the machine thank you for reading!
